Hello Basic
Let's say you do some of the basic examples that come with Windev, create a basic window with a table and some basic code and then come back to us if that doesn't work

Hello Basic
You can set a filter on a file an dthen direct fill a table with the results by binding the table to the file, or you can run a query and the use filetotable or you can use Hreadseek() in a do while loop
Tyr the CRM example or try running the RAD in procedural code. It will build an entry screen and a view table. The code example is not that bad

Hi Basic,
If I where you I would study query as the source of data, and a Equals Parameter on "Group" (and perhaps a contains parameter on Name)
Nice feature of query parameters is that: "If you not set the parameter, it is not taken into account."
In this way you have a query that can sort on a group, and if the pName parameters is set, you get the a customer within that group that matches your pName criteria
.
And if you use only the pName parameter you have a search on customers name.
So one query can have multiple uses in your code.
Your code would then look something like:
//Defined parameter in the query with the query builder Qry_Customers.pGroup = "A" if hexecutequery(qry_Customers,hdefault) = True For each Qry_Customers //Do something with the data - fill a combo / Popup etc. Trace(qry_customers.name,qry_customers.group) End else Error("Something went wrong, got error.: "+herrorinfo()) end
With queryes you can display the retrived data before you write a single line of code 
Cheers
